B.1) Storage:
-------------
AL32UTF8 is a varrying width characterset, wich means that the code for a
character can be 1 , 2 , 3 or 4 bytes long.
This is a big difference with charactersets like WE8ISO8559P1 or WE8MSWIN1252.
There a character always 1 byte.
US7ASCII characters (A-Z,a-Z,0-1 and ./?,*# etc..) are in UTF8 1 byte, so for
most West european languages the impact is rather limited as only "special"
characters like ç, ñ , é will use more bytes then in a 8 bit characterset.
But if you convert a Cyrillic or Arabic system to AL32UTF8 then the data will
take considerable more bytes to store.
